Is the Universe a Computer Simulation?

dannym3141 says...

I would like to see those links, but they do not link correctly.

New scientist

Wired

Found them. What struck me as most relevant about either of the articles is from the Wired article that basically says, in the penultimate paragraph, that this finding doesn't necessarily mean anything because 1) there may be physical laws or phenomena that we do not yet understand governing the behaviour and 2) we know how a lattice works in our computer simulations - we do not know how a lattice might work if one were to physically exist, why should it act like anything we know?

However, it is a real possibility.

Super-Strong Tiny Robots Pull Heavy Loads

entr0py says...

I think because it's meant to go along with their article, not to be watched on it's own.

The details are pretty amazing though.

"The most impressive feat of strength comes from a ground bot nicknamed μTug. Although it weighs just 12 grams, it can drag a weight that's 2000 times heavier – "the same as you pulling around a blue whale", explains David Christensen – who is in the same lab."

How is this accomplished?

Is it just thanks to nanoadhesion?

Why do so many videos nowadays demonstrate cool stuff without any sort of explanation. Down-vote!

Bionic arm gives cyborg drummer superhuman skills

Zawash says...

From the article:
For Barnes, the device needed to be able to take cues from the human body. The lab designed a prosthesis that uses a technique called electromyography to pick up on electrical signals in the upper arm muscles. By tensing his biceps, Barnes controls a small motor that changes how tightly the prosthetic arm grips the drumstick and how quickly it moves, vital skills for a drummer.

The researchers then added another layer of complexity: a second, autonomous drumstick on the robot arm (see photo). This second stick, controlled via its own motor, uses a microphone and an accelerometer to sense the rhythm Barnes is playing, as well as music from any nearby musicians. An algorithm then produces a new beat with a complementary rhythm and melody, modelled on the music of jazz greats like John Coltrane and Thelonious Monk.

With this extra artificial intelligence, human and machine combine to make Barnes a kind of "superhuman drummer", Weinberg says.

What does the bill actually say?
The bill bans the abortion of a fetus that is at or over 20 weeks of gestation, except in cases of medical emergency. It also states that gestational age should be defined as "the age of the unborn child as calculated from the first day of the last menstrual period of the pregnant woman."
That starts the fetal clock an average of two weeks before the fetus actually exists. The purpose of a menstrual period is to get rid of an unfertilised egg, plus all the tissue that has built up in the womb to support it. A new egg typically reaches the uterus two weeks later. In practice, the law therefore bans abortions as early as 18 weeks into the fetus's development.
Does that definition of gestational age make any sense?
More than you might think. Most doctors count how many weeks a pregnancy has progressed starting from the woman's last period.
"It's been the convention for generations to measure the length of pregnancy from the first day of the last period," says medical ethicist Farr Curlin of the University of Chicago, Illinois. He says it is hard for women to pin down what day fertilisation may have occurred, but can easily remember the first day of their last period.

I can pinpoint about when a woman got pregnant. The gestation period for a fetus is 10 months (I know pretty crazy huh...but it is). So 10 months ago from the point at which they gave birth and the fetus becomes a Human Being, that is when they have gotten pregnant.

It's interesting to me all this talk about weeks and months when "God" gives us a nice perfect line in which to judge these things. Birth. When you are born is when you cease to be a part of your mother and have to crawl out of the womb ready to join the workforce. So lets stop arguing about viability of the fetus...if Conservatives cared about what doctors had to say they would've paid attention in school. Life begins at Birth, fuck off.

Inside 9/11: Who controlled the planes?

marbles says...

>> ^Stormsinger:

>> ^marbles:
Airplanes Have Been Flown By Remote Control Since 1917
One day after 9/11, an article appeared in a top science and technology news service stating “hijackings could be halted in progress with existing technologies, say aviation researchers”. The article quoted a transportation expert as saying:
“Most modern aircraft have some form of autopilot that could be re-programmed to ignore commands from a hijacker and instead take direction from the ground . . . .”
See also this article, in which the former head of British Airways “suggested . . . that aircraft could be commandeered from the ground and controlled remotely in the event of a hijack.
...
While some claim that remote control played a part in 9/11, a separate – but equally interesting – question, is whether remote control could and should have been used to safely land the hijacked airplanes. Given that Al Qaeda flying planes into the World Trade Center and Pentagon was wholly foreseeable, and hijackings could be stopped using existing equipment, why wasn’t the equipment used to stop this type of attack? In other words, why didn’t ground control have the ability to override the hijacked airlines to safely land them and take control of the aircraft?

Which do you think is going to be more common...terrorist hijackings, or script kiddies exploiting security holes in the software?


huh?
